[IGS-DCWG-208] Infrastructure Committee business

[Nacho Romero]

Hello to all of you,

In the end I will not make the trip to the AGU in SF this December and I 
cannot host the IC/DC meeting that I had asked you about a few days ago. 
On the other hand if there is quorum we could still hold the meeting if 
enough people are making the trip and the others we can join by telecon. 
Please let me know and I can get the IGS CB to find a meeting room and 
setup the webex.

Secondly I would ask you to please read the enclosed document from the 
CDDIS on the high-rate data long term archiving. This corresponds to 
Recommendation 2018-02 from last year's IGS Workshop. CDDIS will take 
the lead but we should have discussion and agreement that this appears 
OK to everyone. This way forward shall not be an imposition for the Data 
Centers (as far as I understand) but rather an alternative for storing 
the 96 high-rate station files each day in a much more convenient form, 
so this alternative shall be informed to the users and documented and 
explained on our different websites.

We have a volunteer to start to tackle recommendation 2018-04 and I am 
hoping that we have a plan to announce the switch away from the 
"compress .Z" to "gzip .gz" for IGS data and products, there are some 
issues to work through so if you have ideas or potential pitfalls please 
let us know.

This is related to the removal of the need to submit Rinex 2 files , for 
now we have kindly asked all station operators in the IGs to retain 
Rinex 2/ Rinex 3 capabilities for their stations and many have done so. 
some have already removed the Rine x2 data flows as they updated their 
data handling software and could not retain the old capabilities. By 
making a formal announcement soon that from 01/01/2020 IGS stations do 
not need to submit Rinex 2 any longer if the Rinex 3 station files are 
flowing , but that they can retain dual file submissions if they want, 
but then I would like to know if we can request that the Rinex 2 files 
be "gzip .gz" compressed so that we can move forward  ... please send 
your views on this. Thanks.


Please also look over the enclosed recommendations from the last two 
workshops and let us know if you would like to advance any one of them. 
Thanks. Otherwise I will keep trying to push for actions as needed.

Finally, the next IGS Workshop will be at UCAR in Boulder, CO on 14-18 
August, 2020, I hope to see you there!  If there is no objection now 
(please email me) we will retain the current Infrastructure Committee 
composition and organization and bring it up for discussion next summer. 
I am open to any suggestions for changes including my Chairmanship, I 
have been at this for a while and enjoy it and would like to continue 
but if you would like to be considered we can have an internal IC 
process to elect a new Chair ahead of the next workshop.

Hope all is well at your end,

-- 
Best regards,
Nacho
